It's cool along the lines of one of my favorite pop-up books Birdscapes. Available directly through the Althouse-Amazon portal. I just now noticed they've sold 400K copies.

Each double page opens to a different habitat with birds placed within it. An extended audio file plays birds calls. The calls are overlapped. The idea is to match the sound with the bird pictured in the splayed tableau. The book helps you match bird to call two ways including a key in the back, but for the life of me I cannot match bird to call for a single spread, even for the habitat and birds of my own area. It's a great learning instrument for people better at this sort of thing than me. The tiny batteries of my copy were dead on arrival so I enjoyed the book without sound until they were replaced, and then a whole noisy bird world opened up. The sound stops when you turn the page or close it.

@chip Just go ear alone and ignore what the bird looks like. You won't be able to find the bird anyway.

The Peterson Backyard Bird Song is a trivial beginning, then Peterson Birding by Ear. At some point the narrator will begin to be less helpful than the time he takes, and then the Stokes CD set is better.

The narrator though teaches you how to listen, which is important to start.
